  • Patent number: 6477382
    Abstract: A system and method including a flexible paging protocol which adjusts the allocation of resources for paging in response to the amount of actual paging traffic, by increasing resources for paging when paging traffic is heavy and decreasing them when paging traffic is light. A base station transmits a paging packet message over a paging broadcast channel containing a set of paging messages and a next page pointer. The next page pointer identifies when the next set of paging packet message will be transmitted. A user station monitoring the paging channel receives the next page pointer, and, if not being paged, goes to sleep until the next paging packet message is due. When paging traffic is light, paging messages are sent infrequently, freeing up base station resources and allowing the user station to remain asleep longer. When paging traffic is heavy, paging messages are sent more frequently, ensuring rapid response to the pages and reducing the probability of a missed call.

  • Publication number: 20020054577
    Abstract: A method of power control for use in a communications network having plural transceiver communications nodes therein, including, in an initiator node, transmitting a first signal at a first power level to a responder node; in the responder node, measuring and storing, a first signal level for the first signal and a first signal responder noise level; determining responder reception characteristic information; and sending a second signal to the initiator node; in the initiator node, measuring and storing, the second signal signal level and second signal initiator noise level; and sending a third signal to the responder node; in both the initiator node and the responder node, determining a subsequent data transmit signal power and data rate; and transmitting data at the subsequent data transmit signal power and data rate.

  • Patent number: 6301249
    Abstract: A method of transmission error control includes transmitting at least one frame of packet data to a receiving entity during each of a plurality of time frames, and receiving a plurality of responsive messages from the receiving entity. Each of the responsive messages identifies frames of data successfully received during a current time frame and during prior time frames. The method also includes retransmitting each of the frames of data that the responsive message does not indicate as successfully received.

  • Patent number: 6282424
    Abstract: Apparatus for controlling the blocking of a network-supported primary service by a network-supported secondary service sharing the same network router/switch. A controller included in the network's switch/router operates by identifying for each secondary service connection request the likelihood that if it is allocated a router/switch server, a subsequent primary service connection request will be blocked, i.e., denied a server allocation of its own. If the controller determines it is unlikely that allocating a secondary service connection request a server will cause a subsequent primary service connection request to be blocked, it allocates an idle server to a currently pending secondary service connection request at the router/switch.

  • Patent number: 6278706
    Abstract: A method for establishing wireless communication comprising transmitting a request signal indicative of a request to establish communication with an external device external to a wireless communication device; determining at the wireless communication device based upon the request signal whether the external device communicates using a packet transmission protocol or a circuit switched transmission protocol; and if said external device communicates using a packet transmission protocol, transmitting subsequent communications from the wireless communication device directed to the external device using the packet transmission protocol.

  • Patent number: 6243365
    Abstract: A method for transmission continuation control includes establishing a physical transmission link between a first entity and a second entity, and transmitting a first user message from one of the first and second entities to the other of the first and second entities. The method also includes executing a continuation protocol between the first entity and the second entity while maintaining the physical transmission link. The method further includes transmitting a second user message from one of the first and second entities to the other of the first and second entities, and terminating the physical transmission link between the first entity and the second entity after the transmission of the second user message.

  • Patent number: 6078959
    Abstract: Methods and apparatus for queuing subscriber-originated connection requests for respective calls at a server system. A server system in a telecommunications network receives subscriber-originated connection requests for subscriber pending call access to the server system, and thus, the network. Subscriber-originated connection requests are queued at the receiving server system. The server system receiving the subscriber-originated connection request transmits a first message to the respective subscriber originating the connection request upon the server system's queuing of the connection request. Subsequently, upon the server system allocating a connection resource to a queued subscriber-originated connection request, the server system transmits a second message to the respective subscriber.

  • Patent number: 5966372
    Abstract: Methods for controlling the blocking of a network-supported primary service by a network-supported secondary service sharing the same network router/switch.A probabilistic method for resource control identifies for each secondary service connection request the likelihood that if it is allocated a network router/switch server, a subsequent primary service connection request will be blocked, i.e., denied a server allocation of its own. If it is determined that it is unlikely that allocating a secondary service connection request a server will cause a subsequent primary service connection request to be blocked, an idle server is allocated to a currently pending secondary service connection request at the router/switch.

  • Patent number: H2051
    Abstract: A system for providing multiple quality of service classes to a subscriber using a terminal unit includes a gateway operable to communicate with a network and a base station coupled to the gateway. The base station is operable to communicate with the terminal unit over a wireless interface. The base station is also operable to receive a first packet associated with a first application and a second packet associated with a second application from the gateway. The applications are executed by the terminal unit. The base station is further operable to identify a first quality of service class associated with the first packet and a second quality of service class associated with the second packet using quality of service information. The quality of service information is associated with the first and second applications, and at least a portion of the quality of service information is identified by a network address.
